D. Oxidation
Explanation:
In an <em>electrolytic cell</em>, oxidation (the loss of electrons) takes place at the anode. At the cathode reduction takes place.

Answer:
Option (D)
Explanation:
Chlorofluorocarbon is referred to as one of the important greenhouse gas, that is responsible for the depletion of the ozone layer. It was earlier extensively used in the refrigerators, but are later observed that as the CFC molecules are disintegrated in the atmosphere, it gives rise to the elimination of chlorine atoms that destroy the ozone layer, allowing the ultraviolet radiations to enter the earth's atmosphere. So, the use of CFCs has been banned globally by international treaties.
This gas is long-lasting, and remains in the atmosphere for about 20 to 100 years, is not that effective to human bodies, and present in the stratosphere in a very small amount.
Thus, the correct answer is option (D).
